Abstract

Abstract

In this paper, the method of theoretical knowledge, field surveys and laboratory experiments were used to analyze the environmental conditions, development characteristics and mechanism of the Ermanshan landslide in Hanyuan County, selecting the characters of landslide, geological structure, elevation, aspect, slope, earthquake, rainfall and other factors as analysis variables. We combine GIS with fuzzy mathematical evaluation method, develop the landslide stability evaluation plug-in, and then divide the risk regionalization of study area, in order to avoid occurrence of geological hazards in the area, reduce casualties and property losses. The results show that the landslide areas are mainly concentrated on the elevation at about 1600 m and 30° to 50° slope area. With the increase of height and slope, the possibility of landslides is raised.
